The schedule dictated that one top-10 team was going to lose this weekend due to a head -to-head match-up. As it turned out, there was much more chaos in store.

No fewer than six squads ranked 10th or higher went down to defeat, causing the biggest shake-up yet of the 2013 season in the USA TODAY Sports coaches poll, on the day when the first Bowl Championship Series rankings will be released.

The two teams leading the field managed to stay above the fray as top-ranked Alabama smothered Arkansas and No.2 Oregon flew by Washington State. The Crimson Tide claimed 57 of 62 No.1 votes this week, while the Ducks grabbed 4.

The rest of the top 10 was completely rearranged, starting with Florida State moving up to the No.3 spot. The Seminoles turned their top-five battle at Clemson into a 51-14 laugher, a showing impressive enough to earn them their first No.1 vote of the season and their highest ranking since 2003. Florida State leapfrogged fourth-ranked Ohio State, which slipped from the No.3 slot after staving off a stiff challenge from Iowa.

With the carnage in the top 10, most of it coming from the SEC, The Bears reaped the biggest benefits. Baylor's No.5 ranking is its highest since USA TODAY began administration of the coaches poll, and its climb of seven positions matched the biggest jump of the week.

Stock down: South Carolina.

The Gamecocks took the biggest hit, losing at unranked Tennessee, falling 11 places to No.20. Texas A&M, down eight spots to No.15, and LSU, falling from No.8 to a tie for 13th with Oklahoma State, were other SEC victims.

Baylor isn't alone among unbeaten Big 12 squads now in the top 10. The Red Raiders continued their rapid assent with a six-spot jump to No.9.

Stock down: Clemson.

At least the Tigers were able to cling to a top-10 spot, tumbling six spots from their No.4 perch after a disastrous outing against Florida State. It does give the Atlantic Coast Conference three clubs ranked 10th or higher, with No.6 Miami (Fla.) moving in.
